SPECIFICATION forming part of Letters Patent No. 785,655, dated March 21, 1905.

Application led July 18, 1904. Serial No. 217,025.

./ 'o (LM whom it may concern.:

Be it known that I, HIRAM A. BOND, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Shuttle-Moving Devices for Wire-Looms, of which the following is a full, clear, and exact description.

This invention relates to improvements in the shuttle-motion of a loom, and particularly to the class exemplified in the well-known Lyall loom, in which the` carrier for the shuttle is mounted on an endless band or strap, which latter is mounted on and bodily movable with the lay, and having a back-andforth traveling movement across the Warps closely under the shed, the shuttle, however, moving in the shed and being propelled by the carrier, moved by and movable with the band. v

The object of the present invention is to devise an improved means for imparting backand-forth movement to the band for the shuttle-carriage which is especially adaptable for employment onda wire-weaving loom of the particular description set forth in Letters Patent of the United States issued to me October 15, 1901, No.. 684,536, and March 8,

1904, No. 754,192, in which the final portions of the beating-up motions of the lay are by an acquired momentum and not by a positive mechanically-imparted thrust to the end of the battening, and inasmuch as in the weaving of wire-cloth for paper-machines the quality of the product is dependent on the character of the beating-up motion of the lay, which lay is a suspended lay, it is necessary to devise a propulsion means for the shuttlecarriage-carrying band which will be practical and properly coperative with a suspension-lay and which will be so sensitive in action as not to impede the highly-desirable movements of the lay or to impair the operative eiiicency-thereof.

The invention includes, in a loom, the com,- bination, with the lay and the supportingwheels at its opposite ends for the shuttlecarrier band anda gear-wheel having driving connection with one of the band-wheels mounted on and bodily movable with the lay and having an arbor, of a shaft and means for imparting back-and-forth rotary movements intermittently thereto and a gear-wheel in connection with and driven by said shaft, also having an arbor,and a shaft consisting of two sections relatively non-rotatable, but telescopically arranged for distention and contraction, and respectively endwise universaljoint-connected with the arbors of the aforementioned gear-wheels; and the invention furthermore consists in other subordinate combinations of parts and constructions thereof, all substantially as hereinafter more fully described, and set forth in the claims.

In the accompanying drawings so much of an end portion of a loom as is necessary to make apparent the composition of the present invention is illustrated, Figure 1 being an elevation as looking at the end of the lay and showing the novel mechanism cooperatively arranged in conjunction.therewithand with the shuttle-carriage band mounted thereon and bodily movable therewith. Fig. 2 is an elevation of the parts as seen at right angles to Fig. l. Fig. 3 is a view, on a somewhat larger scale, showing the somewhat wellknown relations of the band-propelled carriage, the shed, and the shuttle. Fig. 4 is a perspective view showing parts of the band and the carriage for the shuttle.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents a part of one of the loom end frames, B representing the lay, the swords B2 for which support the lay at their lower extremities, the same being understood as pivotally mounted at the top of Ader the shed, while theshuttle having sup- IOC) porting contact on and to be propelled by the carriage is within the shed, the carriage moving backward and forward alternately and in proper time to occupy positions at the opposite end extensions of the lay outside of the location of the reeds g, and the warps running therethrough. The arbor d, supported in the bracket therefor at one end of theloomlay, has at its extremity the bevel gear-wheel h, and on the horizontally-extending bracket portion 3, which may be regarded as a part of the lay, is a substantially axially-vertical arbor fi, having affixed at its upper end a bevel gear-wheel j' of somewhat greater diameter than said bevel-wheel L.

G represents what, so far as the present mechanism is concerned, may be considered the driving-shaft, and H represents a counter-shaft having the pinion spur-gear 7c thereon and a bevel-gear m thereon. The journal-supporting standard 0 for one end of the counter-shaft H is provided with a yokeshaped bracket 02, having the approximately vertical journalhub 03, through which is mounted for rotation the arbor p2, at the lower end of which arbor is a bevel gear-wheel n, which is in mesh with the aforementioned bevel gear-wheel m on the counter-shaftH.

Intervening between .and connected with the arbors and p2 for the respective bevel gear-wheels j and a isa distensible and contractible shaft J, the same comprising shaftsections 10 and 12, the one telescoping into the other, and while therefore capable of relative endwise movement the two shaft-sections are non-rotatable relatively to each other by being spline-engaged. Each arbor z' and p2 at its end farthest from the respective gearwheel thereby carried is equipped with a half member 13 of a universal joint, the other half member, 14, of each of the universal joints being aflixed on the outer ends of the telescopic shaft-sections 1() and 12.

The aforementioned driving-shaft G has at its extremity closely outside of the end frame of the loom the cam-wheel IWI, the same having within its face the cam-groove, which, as sho'wn in Fig. 1, comprises diametrically opposite concentric and non-working groove portions 15 15 and the relatively intermediate uniting and working groove portions 16 16, N representing a rack-bar, the rack-teeth 17 of which are in mesh with the spur-pinion gear and said rack-bar has somewhat below its upper end the roller-provided cam-stud t, engaging' in the aforementioned cam-groove, and said rack-bar, moreover, has the longitudinal slot s, which has a guiding engagement over the axial end extension g of the drivingshaft, which projects outwardly beyond the face of the cam-wheel M, and the rack-bar is, furthermore, guided and held to mesh with the spur-pinion la by the shoe u. (Seen in Fig. 2.)

In operation one complete rotation of the cam-wheel is effective to drive the carriage D and shuttle from one' side of the loom across to the other side, it after a pause returning to the side at which it was, again pausing, and insuring, because of the shape of the cam, the suitable operating rotary motions in opposite directions of one of the band-supporting wheels f being imparted through the gearing shown and described and the contractible and distensible shaft universal-jointconnected with the gearing proximate to the band supporting and driving wheel fand the counter-shaft t, it being apparent that thc stated connections have the 4capabilities of conforming to the different locations of the lay, (see the dotted-line position of the lay and the changed position and distended condition of the telescopic shaft, Fig. 1,) and all without impediment or detrimentalefect to that character of action of the lay which is especially highly desirable in a loom for weaving certain descriptions of wire-cloth.

In order that theshuttle-carrier may be moved with positiveness across the loom to reach and momentarily pause at its proper position transversely beyond the shed, the band C is provided with a series of evenlyspaced perforations c, in which radial studs w of one or both of the band supporting and propelling wheels f engage.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- l. In a loom, the combination with the lay having supporting-Wheels at opposite ends thereof, and one thereof provided with a gearwheel, the band for the shuttle-carrier, arranged to run around said supporting-wheels backwardly and forwardly, another gearwheel rotatably mounted on the lay in mesh with the gear of the band-supporting' wheel, of a shaft and means for imparting intermittently rotary reciprocatory movements thereto, a gear-wheel on said shaft, and another gear-wheel in mesh therewith, and a shaft comprising telescopic sections endwise movable but non-rotatable relatively to each other, and having respectively universal-joint connections with the arbors of the aforesaid gearwheels stated as in mesh with the gear on the band-supporting wheel and the gear on the first-named shaft.
